Question

How do you graph the equation `y=3x-4`?

Answer 1

graph{y=3x-4 [-10, 10, -5, 5]}

Explanation:

`y` = 3`x` -4

The minus four is where you start the line on the `y` axis, while the `3x` tells you how far you go up per one across the `x` axis.

Answer 2

graph{3x-4 [-10, 10, -5, 5]}
Look at explanation for how.

Explanation:

Okay, so the slope of the line is 3, which means that every 1 unit you move to the right (x-axis) you move up 3 (y-axis). You also have a y-intercept (also called a vertical shift) of negative 4. In a normal graph without the shift, you would start at (0,0), but since you have it your graph starts at (0,-4). After this point, your next one would be (1,-1), then (2,2), and so on and so forth.
